Handbook for 5.x module development guide wrong db_query_range args

The module tutorial has an error if readers are using drupal 5.0 rc1.

This line should be changed from

$queryResult = db_query_range($query, 0, $limitnum, $start_time, $end_time);

to

$queryResult = db_query_range($query, $start_time, $end_time, 0, $limitnum);
